Thank you. It only happened once where more than one shell was released from the mag tube. Std no extension. Most of the time the gun either hangs up feeding the second round or ejects the spent bull and the next live round. The ejector seems to be functioning fine. I have taken the spring out and cleaned it with compressed air,re-lubed and reassembled.
I will order new extractor, spring and ejector spring.
I’ll check the shell fitment.
Thanks for the guidance!
